AS3608
System PMU with HV Back Light Driver
1 General Description
HV Backlight Driver
Step up for 30V backlight with internal transistor
The AS3608 is an ultra compact System PMU with integrated battery charger and HV back light driver.
The device offers advanced power management functions. All necessary ICs and peripherals in a battery powered mobile device are supplied by the AS3608. It features 3 DCDC converters as well as 5 low noise LDOs. The different regulated supply voltages are programmable via the serial control interface.
The step-up converter for the backlight can operate up to 30V. Both constant voltage (OLED supply) as well as constant current (white
LED backlight) operations with 2 current sinks are possible. An internal voltage protection is limiting the output voltage in the case of external component failures.
AS3608 also contains a Li-Ion battery charger with constant current and constant voltage. The maximum charging current is 1A. An integrated battery switch and an optional external switch are separating the battery during charging or whenever an external power supply is present. With this switch it is also possible to operate with no or deeply discharged batteries. A programmable current limit can be used to control the maximum current used from a USB supply.

8 Detailed Description - Power Management Functions
8.1 Low Drop Out Regulators
These LDOs are designed to supply sensitive analog circuits, audio devices, AD and DA converters, micro-controller and other peripheral devices. The design is optimized to deliver the best compromise between quiescent current and regulator performance for battery powered devices.
Stability is guaranteed with ceramic output capacitors of 1µF ±20% (X5R) or 2.2µF +100/-50% (Z5U). The low ESR of these caps ensures low output impedance at high frequencies. Regulation performance is excellent even under low dropout conditions, when the power transistor has to operate in linear mode. Power supply rejection is high enough to suppress high ripple on the battery at the output. The low noise performance allows direct connection of noise sensitive circuits without additional filtering networks. The low impedance of the power device enables the device to deliver up to 150mA even at nearly discharged batteries without any decrease of performance.

8.1.1 LDO5
This LDO generates the digital supply voltage used for the PMU itself.
Input Voltage is VSUP5
Output Voltage is VDD27 (typ. 2.7V), this LDO always starts at the beginning of the start-up sequence as it is needed for all further operation. The default voltage cannot be changed in the boot ROM.
Driver strength: 100mA, can be programmed to 200mA
It is set to a default output voltage of 2.7V, 100mA max
. It supplies the analog and digital part of the PMU. Additional external loads are possible but must not exceed the supply ratings in total together with the operating internal blocks. Further, the external load must not induce noise to the
VDD27.

8.2.1 Functional Description
The step-down converter is a high efficiency fixed frequency current mode regulator. By using low resistance internal PMOS and NMOS switches efficiency up to 97% can be achieved. The fast switching frequency allows using small inductors, without increasing the current ripple. The unique feedback and regulation circuit guarantees optimum load and line regulation over the whole output voltage range, up to an output current of 700mA, with an output capacitor of only 10µF. The implemented current limitation protects the DCDC and the coil during overload condition.
To achieve optimized performance in different applications, adjustable settings allow to compromise between high efficiency and low input, output ripple:
Low Ripple, Low Noise Operation (current force mode = OFF).
In this mode there is no minimum coil current necessary before switching off the PMOS. As result, the ON time of the PMOS will be reduced down to tmin_on at no or light load conditions, even if the coil current is very small or the coil current is inverted. This results in a very low ripple and noise, but decreased efficiency, at light loads, especially at low input to output voltage differences. In the case of an inverted coil current the regulator will not operate in pulse skip mode.

DVM (Dynamic Voltage Management).
To minimize the over-/undershoot during a change of the output voltage, the DVM can be enabled.
With DVM the output voltage will ramp up/down with a selectable slope after the new value was written to the registers. Without DVM the slew rate of the output voltage is only determined by external components like the coil and load capacitor as well as the load current.
Fast Regulation Mode.
This mode can be used to react faster on sudden load changes and thus minimize the over-/undershoot of the output voltage. FRM needs an 22uF output capacitor instead the 10uF one to guarantee the stability of the regulator.
Low Frequency Operation.
Especially for very low load conditions, e.g. during a sleep mode of a processor, the switching frequency can be reduced to achieve a higher efficiency.
100% PMOS ON Mode for Low Dropout Regulation.
For low input to output voltage difference the DCDC converter can use 100% duty cycle for the PMOS transistor, which is than in LDO mode.

8.3 30V Step-Up DCDC Converter
The integrated Step-Up DC/DC Converter is a high efficiency current-mode PWM regulator, providing an output voltage up to 30V. A constant switching-frequency results in a low noise on supply and output voltages.
It has two programmable high voltage current sinks (0 to 38.25mA) for driving e.g. white LEDs as back-light. It can drive also unbalanced strings due to the internal automatic feedback selection.
A voltage feedback mode allows generating constant supply voltages for e.g. OLEDs. The output voltage is set by an external resistor divider and an internal current sink.
An internal protection circuit will shut down the regulator if the voltage on FBSU exceeds the over voltage threshold. No more external protection has to be used to avoid an exceeding of the operation conditions in a no load situation.

8.3.3 Over Voltage Protection (OVP) content
= 1 enables feedback via the current sink pins. The voltage on the current sink pin is regulated to
selection of the current sink with the larger load is done automatically. The pin FBSU acts as an overvoltage protection in this mode. Please be sure to set the voltage to a higher level than needed to drive the longer LED string. The calculation of the resistor can be done the same as described in the chapter above.
8.3.4 DLS & Dimming
AS3608 feature external dimming inputs via CURR1, CURR2, GPIO1 or GPIO2 by directly connecting a PWM output of e.g. the display controller for DLS (dynamic luminance scaling). Manual dimming can be done at any time by setting the sink current via I2C commands.
8.3.5 Current Sinks
The current sinks work independent from each other and can also be used without the booster, or can act as a dimming input if they are not needed as a sink.

8.4 Charger
This block can be used to charge a 4V Li-Ion accumulator. It supports constant current and constant voltage charging modes with adjustable charging currents (94 to 1000mA) and maximum charging voltage (3.9 to 4.25V).
The charger consists basically of a pre-regulator, which limits the current from e.g. the USB input and provides a constant VSUP after reaching
EOC (end of charge) and the battery switch, which is controlling the current into the battery.
Input Voltage of the pre-regulator: VUSB
Output of the pre-regulator and input for the battery switch and system supply: VSUPSW
Output of the battery switch and battery terminal: VBATSW
CVM (constant voltage), CCM (constant current) and trickle charging

8.4.2 End of Charge Detection content
8.4.3 VSUPSW and Temperature Supervision
The charger will automatically reduce the charging current if VSUPSW drops below the selected level. It will automatically stop charging when the chip temperature gets too to hot. The charger will return to normal operation as defined in the charger registers if VSUPSW and the chip temperature return to their normal operating range.
8.4.4 Battery Temperature Supervision
This charger block also features a supply for an external NTC resistor to measure the battery temperature while charging. If the temperature is
too high (voltage on BATTEMP pin is below
) the charger will stop operation. If needed an interrupt can be generated based on
this event. When the battery temperature drops the charger the voltage on BATTEMP pin will rise above
and the charger will start charging again. This is forming a temperature hysteresis of about 3 to 5°C to avoid an oscillation of the charger.
The levels for switching off the charger (45ºC or 55ºC) as well as the type of NTC (10k or 100k) can be selected via register settings. The battery
temperature supervision via the NTC can be switched off (
Technical
If the charger state machine reaches EOC 2 times within a very short period it assumes that there is no battery connected to the VBATSW terminal.
After this a sensing current of 1uA is applied to the BATTEMP pin to detect if a battery is reconnected.

9.1.2 Start-up Sequence
The start-up sequence is defined in the boot ROM and will be fixed during the production test.
The sequence and voltage of the regulators can be freely chosen for the start-up sequence with the following limitations:
VDD27 will always start-up, after a ~5ms delay the sequencer will start-up the other chosen regulators with either 0, 1 or 4ms delay each.
A maximum of 6 regulators (no matter of DCDC or LDO) or 5 regulators and a changed GPIO configuration can be chosen for the start-up.
On a 7th time-slot PVDD2 can be started-up, but has reduced setting on the output voltage
PWRGOOD will be activated ~3ms after the last regulator.

9.3.1 VSUP Supervision
The VSUP supervision has a selectable level. If the shutdown is not enabled an interrupt can be generated.
9.3.2 VDD27 Supervision
If VDD27 reaches the “programmed level of VDD27” -10% for typ. 3ms, the PMU shuts down automatically. If the shutdown is not enabled an interrupt can be generated.
9.3.3 Junction Temperature Supervision
The temperature supervision level can also be set by 5 bits (120 to –15ºC). If the temperature reaches this level, an interrupt can be generated.
The over-temperature shutdown level is always 20ºC higher. This shutdown can be disabled in Reg. 20h.

9.4 Interrupt Generation
All interrupt sources can get enabled or disabled by corresponding bits in the 4 IRQ-bytes. By default no interrupt source is enabled.
The XIRQ pin can be configured to operate in push/pull (2 different driver strengths), open-drain mode or to be tri-state. The signal polarity can be defined as active-low or active-high. Default state is open-drain active-low.
9.4.1 IRQ Source Interpretation
There are 3 different modules to process interrupt sources:
LEVEL.
The IRQ output is kept active as long as the interrupt source is present and this IRQ-Bit is enabled.
EDGE.
The IRQ gets active with a high going edge of this source. The IRQ stays active until the corresponding IRQ-Register gets read.
STATUS CHANGE.
The IRQ gets active when the source-state changes. The change bit and the status can be read to notice which interrupt was the source. The IRQ stays active until the corresponding interrupt register gets read.De-bouncer
There is a de-bounce function implemented, a de-bounce time of 3ms is selected per default in the IRQ_ENRD_3 register (26h).

9.4.2 Interrupt Sources
These IRQ events will activate the XIRQ pin:

Description
The output will be high when the charger is no active. The output toggles between high and low as long as the charging is on going. If EOC, a timeout or overtempertur event stops the charger the output stops toggling.
The output will be high when the charger is no active or in EOC; it will be low if the charger is active.
ams
The output will be high about 3ms after the start-up sequence is finished. It will be low during the sequence. Please be sure to configure the GPIO before the pull-up voltage, otherwise the output
The output will get low if the VSUP undervoltage level is reached.
The output will be high.
LOW The output will be low.
Please note that all GPIO pins are open-drain outputs. They can only output a logic “high” if a pull-up and the corresponding pull-up voltage is present.

Random Read and Sequential Read are combined formats. The repeated START condition is used to change the direction after the data transfer from the master.
The word address transfer is initiated with a START condition issued by the master while the bus is idle. The START condition is followed by the device-write address and the word address.
In order to change the data direction a repeated START condition is issued on the 1st SCL pulse after the acknowledge bit of the word address transfer. After the reception of the device-read address, the slave becomes the transmitter. In this state the slave transmits register data located by the previous received word address vector. The master responds to the data byte with a not-acknowledge, and issues a STOP condition on the bus.

Random Read, for a sequential read the transferred register-data bytes are responded by an acknowledge from the master. The number of data bytes transferred in one sequence is unlimited (consider the behavior of the word-address counter). To terminate the transmission the master has to send a not-acknowledge following the last data byte and generate the STOP condition subsequently.
